Door sensors make a noise?

I’m wanting door sensors to work with ST.
My current simplisafe ones make a noise when doors open and close.
Do ones like iris make a beep or anything to indicate open/close? Do I need a separate thing to alert me?

They do not. You would need a separate device to act as a chime. The Dome siren has several chimes you could use with rules setup in SmartThings.
